my name is Tristan so when I saw these headphones I had to get them. The first time I put them on I listened 2 music for like 7 hours and my ears weren't sore at all. Kickin sound definitely recommend.
I've had these headphones going on 3 weeks now, & have not had any problems with them whatsoever. The sound quality is amazing. One complaint I have read is not being able to use them passively without battery use. Just invest in some rechargable batteries & it shouldn't be an issue. There is some noise leak if you crank up the volume. This isn't an issue for me, as I tend to use them as a small speaker in my cubicle. $300 is crazy-pricey for headphones, but the sound quality & noise cancelling totally sold me. Even better was the artist limited edition matte purple finish sold through Apple.
